343 Industries began to send out the Specialization unlock codes Friday evening for Halo 4 owners who played the Xbox 360 shooter online by November 20.

The Halo 4 email being sent out by Xbox LIVE has the subject heading, "Here is your gift from Xbox LIVE" and includes a "Get your free gift" button that you'll need to click. This will open up Xbox.com where you'll need to log in to your Xbox LIVE account. You should see a text entry box pre-filled with a redeem code and you will only need to click the "Redeem Code" button to receive the "Specialization Priority Alpha" DLC that unlocks the six additional Specialization armors for Halo 4 multiplayer.

For those that don't know, Specializations are additional sets of armors and abilities that can be attained after reaching Service Rank 50 in multiplayer. Each Specialization adds another 10 ranks for players to achieve and comes with not only unique armor but special armor abilities or tactical upgrades.

The initial plan was for only those that purchased the Halo 4 Limited Edition to have access to all eight Specializations. Everyone else was to to only have access to two initially with the rest to be rolled out over a span of weeks.
